Ditto on that. The heads of the outer-ring hex screws on the SW hubs are extremely easy to strip. One of several reasons why I feel the Aisin hubs are superior. One thing I suppose you could try before installing them is to pre-grind a thin slot in each one of them using a Dremel tool with a thin grinder disk, that way you could install them with a common screwdriver instead. Still, that's a lot of work for little gain. You'd still have to use very little torque when installing them, lest you strip the threads of the screws themselves.
